- Regression equation: y = 1.2x - 21.3
- Final Answer: 33
=======================================================
Explanation:
I'm not sure how your calculator works, but I'm assuming you can copy/paste the given numbers into the calculator somehow to have it determine the regression equation.
The tool I used is GeoGebra and the regression equation it produced was
y = 1.2x - 21.3
Each decimal value is approximate and rounded to the nearest tenth.
---------------------------
Once we determine the regression line, plug the homework grade x = 45 to find the associated test grade (y). This is a predicted test grade.
y = 1.2x - 21.3
y = 1.2*45 - 21.3
y = 32.7
y = 33
If a student got a 45 on a homework, then we predict their test grade should be around 33.
